WINDSHIELD.

Application filed June 18, 1927. Serial No. 199,723.

My invention relates to a wind shield.

It is the general object of the present invention to provide a secure,relatively simple means for holding a swinging wind shield panel inadjusted position.

It is a further object to provide a wind shield with means for holdingthe swinging panel in adj usted position, which means may be quickly andreadily actuated. with one hand from a point intermediate the edges ofthe wind shield.

It is another object to provide a wind shield with means for bothswinging the movable panel and clamping the same in adjusted position.

It is a further object to provide a wind shield with readily adjustablemeans for holding the wind shield and swinging panel in variouspositions.

()ther objects and features of the invention will appear as thespecification proceeds.

Briefly stated, in the preferred form of the invent-ion I provide theswinging panel with a tubular member serving as the swinging support.Wedge means preferably at both ends of the tubular member serve to holdthe latter and the swinging panel in various positions of adjustment.The wedge means may be actuated by a handle member positioned at anyconvenient point intermediate the edges of the wind shield, and thewedging members imvy be arranged for adjustment so as to come for wear.T he means for actuating the wedge means may be so arranged as to servethe purpose of a convenient handle for swinging the panel: in eitherdirection to thus permit the panel to be swung and clamped with onehand.

In the drawings which show, for illustrative purposes only, a preferredform of the invention- Fig. 1 is a front view of a wind shield;

Fig. 2 is a. fragmentary, vertical sectional view through the swingingpanel. of a wind shield, and illustrating features of the invention Fig.3 a sectional view taken substantially in the plane of the line 3 3 ofFig. 2;

F 4- is a fragmentary, horizontal sectional view of an intermediateportion of a wind shield;

Fig. 5 is a detail view of operative parts of my invention, the variouselements being relatively separated for the purpose of illustration.

In the particular embodiment illustrated, (3 lndicates a frame whch maybe positioned in a closed car and may receive the swinging panel 7.While the invention will be described in connection with a wind shieldfor a closed type of vehicle, it is to be understood that the invent-ionis not confined to closed cars. The swinging panel 7 includes a tubularmember 8 preferably extending from side to side of the panel. Thistubular member 8 serves as the swinging bearing of the panel, and isournaled at the sides upon bosses 910, which may be suitably secured tothe edges of the frame 6 as by means of screws llll. The bosses 910 inthe form shown are extended inwardly, and the inner ends 12-13 haveinclined wedge faces formed thereon, as shown particularly in Figs. 2and 5. Complementary movable wedges 14l15 are positioned within the tube8 and coact with the fixed wedges l213 so that when the wedges 1415 aredrawn inwardly toward each other, the wedge members 12 let and l3-15will be expanded to grip the in ner surface of the tube 8 and thus holdthe swinging panel '7 in adjusted position.

It is desirable to have the control means for the wedge mechanismpositioned intermediate the edges of the wind shield and to have thewedge mechanism at both ends controlled by a means. For theaccomplishment of that end I may employ a tension rod 16 secured to thewedge M and rotatably attached at the inner end to a cam plug 17 havinga cam surface or abutment 18 at the left hand side as viewed in Figs. 2,l and The movable wedge has rotatably secured thereto a tension rod 19extending inwardly and provided at the inner end with a cam plug 20having a cam surface or abutmr-ut 21 thereon. In the form shown, the camplugs 17 and 21 extend in- \vardly to and beyond each other so that thecam surface on each plug is between the cam surface on the other plugand the wedge movable with said other plug. A cam or eccentric 22 ispositioned between the cam surfaces lR-21, and in the form illustratedis journaled upon a pin 23 passing through slots 2l25 in the respectivecam plugs. In order to move the eccentric or cam 22, I preferably employa relatively long arm or handle 26, which is of such size that it may bereadily gripped with the hand. The greater diameter of the eccentricpreferably extends along the same general line as the line of the handle20, so that when the handle is positioned at substantially right anglesto the tube 8, the cam surfaces 18-21 niay approach each other and thusrelease the wedges. When the handle is moved into substantialparallelism with the tube 8 as shown in l ig. 4, the cam surilacesiii-21 will 1 a separated by the cam 22, and the wedges thus caused tohe moved into clamping relation with the tube S. The tube 8 is suitablyslotted at 27' to permit pas-- sage of the actuator 26, and i1? desireda suitable escutcheon plate 28 may be secured to the tube to provide afinished appearance.

In order to conn ensate for wear on the wedge surlaces and to permit ofany necessary zuljustment, I provide means for ad justahly positioningthe wedges relatively to each other. In the term shown, the rod 1!} isthreaded and is provided with an adjusting nut- 29 at its inner end,which nut ala'its a suitable surlace or shoulder on the cam plug 20. Thenut 29 may he provided with recesses 30 'loi. receiving a pin :lorturning the nut. The rod is preferably keyed as at 31 to the plug sothat any rotation. of the plug 20 will not tend to loosen or tighten thenut 29.

When in use, the driver or other occupant Oill the car may, with onehand, grasp the ae tuator 26, and pull the same rearwardly so as torelease the wedging means at the ends oi? the swinging panel. lil a longconvenient handle 26 be provided, as shown in F 4. and 5, the handle maybe employed for swinging the panel in either the opening or closingdirection. hen the panel is in the desired position, the operator, stillgrasping the hendle 26, may move the latter 'lm'wardl y into theposition shown in Figs. eland 5, and thus cause the swinging panel to beheld in the desired position. The actuator 26 may he positioned at anypoint along the tube 8. but is preferably arranged somewhere near thecenter sons to he in coilvenien t reach ol the opera-.

tor of the vehicle. lilince the handle E26 serves to actuate both thewedging means and may be employed l'or swinging the wind shield panel,it will be clear that only one hand of a person is necessary for bothswii'iging and locking the swinging panel in the desired position. Sincethe connection between the plugs 1720 is what may be termed a floatingconnection, equal forces will be impressed upon the two movable wedgesand the wedging lorces at the two ends of the swinging panel. thusequalized.

The parts are all ol relatively simple and sturdy construction, and thedevice is not likely to get out of order. Any adjustment found to henecessary may he readily made by turnin the nut on the rod 1?).

While a preierred term of the invention has been described in greatdetail, I do not wish to be limited to the particular form shown sincemany changes may be made within the scope oi the invention as defined inthe up pended claims.
